This study provides an explanation for the strong resistance to B. cinerea observed in wounded plants or plants with cuticular defects. We have observed that a production of ROS and a permeable cuticle is common to all these situations. ROS, that include hydrogen peroxide, are known inducers of resistance and can also act directly against the invading fungus. Degradation of the cuticle by...
